What Is Gut Health?
Gut health means your stomach and intestines have a balance of tiny living things like bacteria, viruses, and fungi. These are called the gut microbiome.
A healthy gut microbiome:
- Helps digest your food
- Helps your body take in nutrients
- Keeps your immune system strong
- Supports your heart and brain health
If this balance is disturbed, it can lead to many health problems.
What are the main reasons for gut health problems?
Gut problems usually start because of our daily habits. The most common reason is eating the wrong food. Eating too much fried, oily, or fast food reduces good bacteria and increases bad bacteria in the gut. Not drinking enough water, not eating enough fiber, and eating too much sugar or artificial stuff also harm the gut.
Another big reason is stress. When we stay stressed for a long time, our digestion gets affected. This can make the gut work too slow or too fast. Lack of sleep, no exercise, and sitting all day also cause gut problems.
Sometimes, taking too many medicines like antibiotics or painkillers can kill the good bacteria in the gut. This leads to swelling, gas, indigestion, and other problems.
Lastly, eating at wrong times, eating too fast, or not chewing food properly can hurt digestion. This can cause gut health to get worse over time.
By avoiding these habits, we can keep our gut healthy and stop bigger illnesses later.

if gut health gets bad, what diseases can happen?
When the gut is not healthy, many parts of the body can be affected. The good and bad bacteria in the gut must be balanced. If this balance breaks, the risk of many diseases goes up.
The most common disease is Irritable Bowel Syndrome (IBS). People with IBS often have stomach pain, gas, constipation, or diarrhea.
Another serious problem is Inflammatory Bowel Disease (IBD). This causes swelling in the gut. There are two main types: Crohn’s Disease and Ulcerative Colitis. These diseases hurt the walls of the gut and cause symptoms like bleeding, pain, and weakness.SIBO (Small Intestinal Bacterial Overgrowth) is a condition where too many bacteria grow in the small intestine. This causes problems like gas, bloating, and indigestion.
Also, Gastritis means the stomach lining is inflamed. This can happen because of problems in the intestines, especially if a germ called Helicobacter Pylori is present.
Sometimes, Reflux (acid or burning feeling in the chest) can also be a sign of intestinal problems. This happens when stomach acid goes back into the food pipe.
When the intestines are unhealthy, people often face problems like constipation or diarrhea. These issues make daily life hard. Some people also develop food intolerances. For example, they may be allergic or sensitive to milk, wheat, or other foods. This shows there is a problem with digestion.
Small pouches can form on the walls of the intestines, causing pain or swelling. This condition is called Diverticular Disease.
Intestine problems are not only about the stomach. They can also affect the brain, heart, sleep, and mood. Some research shows that bad gut health can cause tiredness, stress, depression, and frequent sickness.
So, keeping the intestines healthy is important not just for digesting food but for overall body and mind health too.
You may suffer from all of these or just a few, they may come and go initially but then continue and worsen over time. These symptoms can leave you feeling miserable and isolated and ruin your every day life.
We at 121 Dietitian can help you…..
We use a Low FODMAP Diet to treat gut problems, especially IBS (Irritable Bowel Syndrome). This diet limits certain foods for some time. These foods can cause gas, belly swelling, pain, or diarrhea in people whose guts don’t digest them well.
Here is how our treatment works:
- We offer a complete 6-week program.
- The patient keeps a food diary to record everything they eat.
- We give full guidance, recipes, and a shopping list, so the patient knows exactly what to eat.
- During the program, certain food groups are slowly reduced or stopped, then slowly added back. This helps find out which foods cause problems.
- Our experience shows that 95% of patients feel better in just 8 weeks.
Our goal is not only to ask patients to avoid foods but to help them eat in a way that is easier and better for their body.
This method is backed by science, and we support patients fully so they don’t feel alone.
